virtual | ~QwtIntervalSymbol () |
A drawing primitive for displaying an interval like an error bar.
Symbol style.
NoSymbol |
No Style. The symbol cannot be drawn. |
Bar |
The symbol displays a line with caps at the beginning/end. The size of the caps depends on the symbol width(). |
Box |
The symbol displays a plain rectangle using pen() and brush(). The size of the rectangle depends on the translated interval and the width(), |
UserSymbol |
Styles >= UserSymbol are reserved for derived classes of QwtIntervalSymbol that overload draw() with additional application specific symbol types. |
QwtIntervalSymbol::QwtIntervalSymbol | ( | Style | style = NoSymbol | ) |
QwtIntervalSymbol::QwtIntervalSymbol | ( | const QwtIntervalSymbol & | other | ) |
Copy constructor.
QwtIntervalSymbol::~QwtIntervalSymbol | ( | ) | [virtual] |
Destructor.
